DRILL COLUMN VALVE CONFIGURED TO BE ATTACHED TO A COATING TO CONNECT THE DRILL TO A CONNECTION METHOD TO PREPARE A DRILLING COLUMN VALVE TO CONNECT A PERFORAGE COLLECTION BE ATTACHED TO A COATING TO CONNECT A DRILLING TO A PROBE AND METHOD TO CONTROL A DRILLING COLUMN VALVE. It is a method and a drill string valve (70, 160) for closing a conduit through which a high pressure fluid flows. The drill string valve (70, 160) includes an elongated housing (162) having an inner cavity (79), a sealing member (56) affixed to a first end (74) of the elongated housing (162), and that the sealing member (56) is disposed within the inner cavity (79) so that a flow of liquid (80) through the inner cavity (79) from the first end (74) to a second end (76) is allowed. a sliding valve (50) configured to slide to and from the sealing member (56) so that when the sliding valve (50) contacts the sealing member (56) the flow of liquid is suppressed; propensity cartridge (90) configured to apply a first force on the sliding valve (50), and a loading mechanism (110) configured to apply a second force on the propensity cartridge (90).
